Getting to Know Your ZyWALL

This chapter introduces the main features and applications of the ZyWALL.

1.1 ZyWALL Internet Security Appliance Overview

The ZyWALL is loaded with security features including VPN, firewall, content filtering and certificates. The ZyWALL’s De-Militarized Zone (DMZ) increases LAN security by providing separate ports for connecting publicly accessible servers. The ZyWALL provides the option to change port roles from LAN to DMZ.

You can also deploy the ZyWALL as a transparent firewall in an existing network with minimal configuration.

The ZyWALL provides bandwidth management, NAT, port forwarding, DHCP server and many other powerful features.

You can add an IEEE 802.11a/b/g-compliant wireless LAN by connecting an access point (AP) to an Ethernet port in a WLAN port role.

See Chapter 46 on page 613 for a complete list of features.

1.2 Applications for the ZyWALL

Here are some examples of what you can do with your ZyWALL.

1.2.1 Secure Broadband Internet Access via Cable or DSL Modem

For Internet access, connect the WAN Ethernet port to your existing Internet access gateway (company network, or your cable or DSL modem for example). Connect computers or servers to the LAN ports for shared Internet access.

The ZyWALL guarantees not only high speed Internet access, but secure internal network protection and traffic management as well.
